Abstract
A baffle for a liquid container, such as a vehicle gasoline tank or the like, is formed of a resilient, cellular foam plastic material placed within the container. The cells of the plastic are interconnected, and the volume of the solid material forming the foam plastic is only a minor portion of the overall volume of the material including its open cells. The plastic material is tightly compressed into a long strip which is surrounded by a casing formed of a thin sheet. The plastic material is chemically inert relative to the liquid, but the casing sheet is substantially soluble in the liquid. A predetermined length section of the strip may be inserted in a container. When liquid is poured into the container, the casing is substantially dissolved to free the compressed material, which resiliently expands to substantially fill the container and form a cellular baffle therein.
